proc_means: Replica of SAS's PROC MEANS

In craigjmcgowan/helpR: Miscellaneous Descriptive Functions

Description

Descriptive statistics for continuous variables, with the option of stratifying by a categorical variable.

Usage

proc_means(df, vars = NULL, var_order = NULL, by = NULL, n = T,
  mean = TRUE, sd = TRUE, min = TRUE, max = TRUE, median = FALSE,
  q1 = FALSE, q3 = FALSE, iqr = FALSE, nmiss = FALSE,
  nobs = FALSE, p = FALSE, p_round = 4, display_round = 3)

Arguments

df	A data frame or tibble.
vars	Character vector of numeric variables to generate descriptive statistics for. If the default (NULL), all variables are included, except for any specified in by.
var_order	Character vector listing the variable names in the order results should be displayed. If the default (NULL), variables are displayed in the order specified in vars.
by	Discrete variable. Separate statistics will be produced for each level. Default NULL provides statistics for all observations.
n	logical. Display number of rows with values. Default TRUE.
mean	logical. Display mean value. Default TRUE.
sd	logical. Display standard deviation. Default TRUE.
min	logical. Display minimum value. Default TRUE.
max	logical. Display maximum value. Default TRUE.
median	logical. Display median value. Default FALSE.
q1	logical. Display first quartile value. Default FALSE.
q3	logical. Display third quartile value. Default FALSE.
iqr	logical. Display interquartile range. Default FALSE.
nmiss	logical. Display number of missing values. Default FALSE.
nobs	logical. Display total number of rows. Default FALSE.
p	logical. Calculate p-value across by groups using aov. Ignored if no by variable specified. Default FALSE.
p_round	Number of decimal places p-values should be rounded to.
display_round	Number of decimal places displayed values should be rounded to

Value

A data.frame with columns variable, by variable, and a column for each summary statistic.

Examples

proc_means(iris, vars = c("Sepal.Length", "Sepal.Width"))
proc_means(iris, by = "Species")
